Dragging element for dragging web materials comprising at least a portion with at least one through cut (2) apt to engage a part (40) of a web material (4) intended to be moved in a direction imposed by the same dragging element that follows a predetermined operating path, said at least one cut (2) is helicoidal.

A joining unit includes: a suction holding member having a suction surface configured to suction an end section of a sheet; a moving mechanism configured to move the suction surface toward an intermediate section of a sheet of a delivery-side original material roll along a path set in advance so that tension is applied to the sheet; and a regulating mechanism that is configured to switch between a regulated state in which a movement of the end section of the sheet with respect to the suction holding member due to the tension is regulated and an allowable state in which the movement of the end section of the sheet with respect to the suction holding member is allowed. The controller switches the regulating mechanism to the regulated state during the movement of the suction surface toward the intermediate section of the sheet of the delivery-side original material roll.

An apparatus is provided for shearing a metallic belt from which electrodes of electric accumulators are formed. The apparatus includes a cutting device able to shear a metallic belt advancing along a sliding path, a first slider positioned upstream of the cutting device and a second slider positioned downstream of the cutting device. A handling system drives the first slider and the second slider cyclically with corresponding outward and return strokes, in order to change the length of the sliding path in such a way as to stop cyclically successive portions of the metallic belt at the cutting device, maintaining constant the advancement velocity of the metallic belt upstream and downstream of the cutting device.

Methods and structures are provided for a dunnage system to facilitate efficient coupling together of supply units of pre-configured sheet stock material, such as, for example, separate units of fanfold stacks of pre-configured sheet stock material, in a manner of continuous supply with a continuous pocket extending longitudinally between the separate supply units, so that they can interact with an expander of the dunnage system without disruption as one supply unit is depleted and a next supply unit is fed through the dunnage system. Also, various methods, apparatus, and systems are provided to facilitate smooth operation of a dunnage machine of the dunnage system to reduce a tendency of the pre-configured sheet stock material to jam and to increase the tendency of dunnage product generated to reflect a desired shape and stability.

The invention relates to a transport device (10) for a beginning or an end of a web, comprising at least one driver (27) for a beginning or an end of a web (1). The transport device (10) is largely guided on a horizontal plane from a front region to a rear region of a system. The transport device (10) is to be improved such that smaller quantities of impregnated decorative paper can be produced with little complexity and minimum waste. For this purpose, the driver (27) comprises a plate-shaped magnet (22) which is guided below the web (1) during the operation of the transport device (10), extends over at least the width of the web (1), and interacts with a magnetizable sheet-metal plate (23) during the operation of the transport device (10), said sheet-metal plate being movable above the web (1) from a rest position into a holding position.
